3 Claims.

This invention relates to cooling devices, and its general object is toprovide a device for cooling liquids in an easy and expeditious manner,without the cooling medium coming in contact with the liquid, with theresult the liquid retains its full strength and flavor and contaminationby the cooling medium is impossible.

A further object of the invention is to provide a cooling device that isnot only capable of cooling liquids quickly, but will retain the sarfiecold for a prolonged period of time Without attention.

Another object of the invention is to provide a cooling device withwhich ice can be used as a cooling medium, and while the device can bepacked with very little effort, the ice is completely enclosed, whichnot only retards melting, but the ice is hidden from View.

A still further object of the invention is to provide a cooling devicethat is primarily designed for cooling liquids for use as drinks, suchas cocktails and the like and the device is simple in construction,inexpensive to manufacture and extremely eflicient in use and service.

This invention also consists in certain other features of constructionand in the combination and arrangement of the several parts, to behereinafter fully described, illustrated in the accompanying drawing andspecifically pointed out in the appended claims.

In describing our invention in detail, reference will be had to theaccompanying drawing wherein like characters denote like orcorresponding parts throughout the several views, and in which:

Figure 1 is an elevation of the device which forms the subject matter ofthe present invention.

Figure 2 is a vertical sectional view taken therethrough with parts inelevation.

Figure 3 is a sectional View taken approximately on line 3-3 of Figure2, looking in the direction of the arrows.

Figure 4 is a sectional view taken approximately on line 44 of Figure 2,looking in the direction of the arrows.

Figure 5 is a fragmentary sectional view illustrating a portion of thefollower or packing means.

Referring to the drawing in detail, the reference numeral I indicatesthe base of our device and which includes a bottom wall 2, the latterhaving formed therewith and rising therefrom in graceful curves, theupper portion of the base which is restricted adjacent its upper end andthreaded as at 3.

Threadedly received by the threaded upper end of the upright portion ofthe base I is the restricted lower end 4 of a shell 5, the latter beingoutwardly bulged in rounded formation and the bulged portion extendsinto an outwardly 5 inclined portion 6 that terminates in a horizontallydisposed annular bead 'I having recesses 8 arranged at intervals on thelower surface thereof and following its curvature as clearly shown inFigure 3. 1

The shell acts in the capacity as a bowl to receive a cooling mediumsuch as ice, as indicated in Figure 2, and also received in the shell 5is a substantially cup-shaped member 9 that is tapered toward its lowerend in order to provide ample space between the same and the wall of theshell, so that a substantial quantity of ice or the like can be disposedbetween the wall of the member 9 and the shell.

The member 9 is suspended within the shell and for that purpose, themember 9 has formed with its upper end an annular tongued portion I9that overlies the bead I and is directed to the under surface thereof asclearly shown in Figure 2 to contact bearings I I such as balls disposedwithin the recess 8, with the result there will be antifriction meansbetween the tongued portion I0 and the bead in order to allow for easyrotation of the cup-shaped member with respect to the shell, as will beapparent upon inspection of Figure 2. The cup-shaped member 9 is rotatedthrough the instrumentality of a handle I2 that is secured to and risesfrom the tongued portion It], therefore it will be obvious that the usercan grip the handle I2 and revolve the cup-shaped member.

We also employ means for retaining the cooling medium in packedassociation about the cupshaped member and that means includes a disk I3that has threadedly secured and depending therefrom sleeves I 4, thelatter being telescopically mounted on posts I5 which are fixed to andrise from the bottom wall 2 of the base I. The sleeves I 4 are eachprovided with diametrically disposed vertically arranged slots I5 withinwhich rides the ends of pins I1, there being one pin for each post andthese pins extend through the posts as clearly shown in Figure 5, withthe result the pins and slots act as means to limit the slidablemovement of the sleeves on the posts, and surrounding the sleeves andposts are coil springs I8 which have their end convolutions engaging thebottom wall 2 and the disk I3 respectively, as best shown in Figure 5.The coil springs urge the disk upwardly, so that the cooling medium willbe disposed at all times in contact with the outer surface of thecup-shaped member 9'.

The disk I 3 is provided with a plurality of openings [9 to allow forthe passage of water in the event'that ordinary ice is used as a coolingmedium, but of course it will be understood that dry ice or any othermeans can be used for that purpose.

From the above description and disclosure of the drawing, it will beobvious that we have provided a cooling device that is capable forcooling liquids for use as drinks and the like, in an easy andexpeditious manner, as the device is filled with ice and the like, thenthe cup-shaped 'member which is used to receive the liquid is rotatedthrough the instrumentality of the handle l2. V

The device can be made in any size desired and from any material, in anydesign and not. Only acts as a sufficient cooling means, but also isornamental in appearance. a r 1 v It is thought from the foregoingdescription that the advantages and novel features of our invention willbe readily apparent. r

'We desire it to .be understood that we may make changes in theconstruction and in the combination and arrangement of the severalparts, pro vided thatsuch changes fall within the scope of the appendedclaims.

What we'claim is: V

1.IA cooling device comprising a shell, base means for closing the lowerend of the shell and being detachably secured thereto,liquid'receivingmeans connected to and closing the upper end 'oftheshell and mounted for rotation thereon,

said shell being adapted to receive a cooling means and having theliquid'receiving means suspended therein, and spring pressed means forretaining the cooling medium about the liquid receiving means andmounted in the base means.

2. A cooling device comprising a shell having ceive' a cooling mediumwith the cup-shaped member suspended therein, and spring pressedmeans'arranged in the base means for retaining the cooling medium aboutthe cup-shaped member. 7 V r 3. A cooling device comprising a shellhaving open upper and lower ends, base means closing the lower end anddetachably secured thereto,'a

substantially cup-shaped member suspended into the shell'and having itsupper end disposed about the upper end of the shell for connectiontherewith and for rotation with respect thereto, means by which thecup-shaped member may be rotated, said shell being adapted to receivea'cooling medium fordisposal about the cup-shaped member,

and means including a spring pressed apertured disk mounted in the basemeans for retaining the cooling medium about the cup-shaped member. 7 V
